Can't Turn Sound Back On!
I can't turn my sound back on when using internal speakers and don't know what I did to "lock it off."
Everytime I hit the volume keys to turn on/off or to adjust up/down, a small icon pops up with a slash through a circle.
I'm not getting any sound in any applications and already tried restarting my MacBook, resetting PRAM, etc.. Sound only works with headphones, ext. speakers, or anything that can output sound that can be connected to my headphone jack. Oh, and one more thing... why is there a red light beaming out of the headphone jack? I noticed it was a red light when my room was dark one time. Whenever I take the headphones or speaker cord out of the jack, that light shows up. Does this mean something is malfunctioning?
Any help would be most appreciated!
